hi everybody..
please give me solution for follwing.

i m interfacing dm9000 ethernet controller ic with
microcontoller

i have used memory mapping for interfacing it.

cmd pin is connected to adress line A2
Chip sellect CS is generated by A17=0,A18=1,A19=0
AD0 to AD15 lines are used for address data port of
dm9000
 so veriable DMADDR is at address 40000h
& DMDATA is at address 40004h;

Read write lines of microcontroller are properly
connected to dm9000

in this way can i access the address & data ports of
dm 9000 by accessing DMADDR & DMDATA?


Please help!!!!


Regards

Rohan Patil
